Four point contact ball bearing

The four-point contact ball bearing is the kind of bearing which can be separable. The 0000 type has a double semi-inner ring, and the OJ0000 type has a double semi-outer ring, and the contact angle is 35°. When there is pure radial load or no load, the steel ball and the ring are in four-point contact; under the action of pure axial load, the steel ball and the ring are in two-point contact and can withstand bidirectional axial load. This type of bearing can also withstand moment loads and combine the functions of single row and double row angular contact ball bearings. This kind of bearing can only guarantee normal operation when two-points contact is formed.

MACHINE TOOL

Machine tool is the carrier of advanced manufacturing technology and the basic production means of equipment industry. It is the basic equipment for equipment manufacturing industry, mainly for automobile, military, agricultural machinery, engineering machinery, electric power equipment, railway locomotive, ship and other industries. Machine tool performance plays an increasingly important role in production efficiency and product quality and also has high demand for more reliable and energy efficient components.

MOTORCYCLE

Each motorcycle is usually equipped with 20 to 30 bearings. These bearings are used for important rotating parts such as engines, transmissions, and wheels to support driving, and are responsible for reducing friction and driving the engine power to the wheels. Therefore, the performance required for motorcycle bearings is to achieve smooth rotation through low friction, low vibration and high durability. These performance affect the fuel consumption and safety that are closely related to our life. ZYS always pays attention to these details and strives to develop bearing and optimize the bearing design to improve the quality of life and protect the global environment.
